And rightly so, since registerDeviceNotification() does not exist.
$w0rdf1$h wrote: ...but my program is also not working..im not getting any notification...
Why would you expect to?
$w0rdf1$h wrote: i can do this using win32 api with winMain()...
Probably so (assuming you capitalized it correctly), since it likely has a message pump.

What does that have to do with using main() in place of WinMain()?

see i found it on MSDN that function registerDeviceNotification(...,...,... )
registers for windows service that sends notification to window whose HWND is registered( passing it as a parameter)....and its a function in WIN32 API.. so y should i get a no such function exist error...
see this...

C++ is case sensitive, so registerDeviceNotification is not the same as RegisterDeviceNotification.

Could you please write in proper english ? A lot of people here are not native english speaker and deciphering SMS messages is really a pain.
For your question: did you include Winuser.h ?
And, why do you want absolutely use windows API in a console application. You don't have a message loop so how could you receive windows notification messages ? David already told you so.
Why don't you simply create a Win32 app, create a window and don't show it ?

Now I am using WinAPI and not using console.....
i have created a window and hide it using showWindow(hwnd,0) and this is working fine...now no need to panic... thanx....

Can anybody help me help me to remove and add Caption Bar of a dialog at runtime.
I have created a dialog through resource with a caption bar.
I want to remove completely the caption on clicking the Button1 on the dialog and add the caption bar on click of button2 on the dialog.
Though on click of Button1 the caption bar is still there but the dialog is not movable whereas when i click Button2 I am able to move the dialog on selecting the Caption bar.
Can anybody suggest the way where the caption will be completely removed and caption appears as per our requirement.
void CCaptionWndDlg::OnButton1()
{
ModifyStyle(WS_BORDER|WS_CAPTION,0);
CRect aRect;
GetWindowRect(&aRect);
::SetWindowPos(m_hWnd,HWND_TOP,aRect.top,aRect.left,aRect.Width(),aRect.Height(),SWP_NOZORDER | SWP_NOACTIVATE);
}
void CCaptionWndDlg::OnButton2()
{
ModifyStyle(0, WS_BORDER|WS_CAPTION);
CRect aRect;
GetWindowRect(&aRect);
::SetWindowPos(m_hWnd,HWND_TOP,aRect.top,aRect.left,aRect.Width(),aRect.Height(),SWP_NOZORDER | SWP_NOACTIVATE);
}

replace with
::SetWindowPos( m_hWnd, 0,0,0,0,0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOZORDER|SWP_DRAWFRAME );

Thanks a lot Naveen.. SWP_DRAWFRAME did the trick.

FYI: SWP_DRAWFRAME can be specified in the ModifyStyle itself

Ya I forgot. BTW ModifyStyle() internally does the same thing...

The following code will do the trick... 
void CCaptionWndDlg::OnButton1()
{
ModifyStyle( WS_BORDER | WS_CAPTION, 0, SWP_DRAWFRAME );
}
void CCaptionWndDlg::OnButton2()
{
ModifyStyle( 0, WS_BORDER | WS_CAPTION, SWP_DRAWFRAME );
}

SWP_DRAWFRAME can be specified in the ModifyStyle itself. So no need to call SetWindowPos explicitly. See the MSDN documention for more details.

... or supported MIME-Types?
I try to code a tiny Multimedia-App (which also uses DirectShow). For error handling, i need to know something about the capabilities of the desired Viewer (supported Audio- / Videocodecs). Any idea, how to get a list of installed codecs on the local machine? I dont know where to look :-|
Hints are very welcome :-|
|
|

I think you should be able to know installed software (i.e. codecs) through browsing in the registry. I can help you much more, bit if you look "registry" in the forum you will find a lot of interestan messages that maybe give you ideas.
hope it helps.
Greetings.

You might be running the unicode version.
change the following option in msdev
tools->options->Debug tab->Tick "Display unicode strings".

In the debug window, you can specify ,su instead of the default value of ,s.
